Even aside from the calling the developers pedophiles, the author seems to just throw a bunch of arguments at the wall, hoping some will land. But there seems to be a deep contradiction: if it's true that the projects all suck and are very far from being useful, then Adobe has nothing to worry about. People only use counterfeits willingly when they're a good replacement for the real thing. You can barely call them a clone if they haven't copied the real differentiators.

Personally, I think what the companies really have to worry about isn't these sorts of clones, but that it won't be long before everyone can just spin up some software that does the 5% of the job that they actually care about. Software gets clunky and bloated because every new feature appeals to somebody; it's just not always the same somebody. So there's a ratchet effect where you can never remove a feature because someone will always complain.
